# render_anim.sh - render a scene scene as animation
# ==============================================================================

# calling conventions:
#
# render_anim.sh [output_directory] scene_file
#
# output_directory: directory where to write the rendered images and animation
# scene_file: scene to render
#
# if an ini file with the same basename as the scene_file exists this is
# used for rendering the animation. Otherwise the render options have to be
# given as a '//' comment within the first 50 lines of the file. There must
# be a space after the '//' and the first option has to start with '-' or '+'.
#
# The scene is rendered into a set of png files and then compiled to an mpeg
# using ffmpeg (which has to be available in PATH). The png files are deleted
# afterwards if the animation has been generated successfully.
# ==============================================================================
# --- specify additional render options here ---
